Create a debug mscorlib?

[high6]

Well I came across an interesting article.

http://www.codeproject.com/KB/dotnet/Debug...rk_Classes.aspx

It is a bit old but with some modifications it works.

I was reading about sequence points http://blogs.msdn.com/jmstall/archive/2004/10/03/237137.aspx.

Is there any ways with ilasm to maximize sequence points?

When debugging I stepped into Thread.Sleep() and got (from the il file I had created from that first link).

  .method public hidebysig static void  Sleep(int32 millisecondsTimeout) cil managed
  {
	// Code size	   7 (0x7)
	.maxstack  8
	IL_0000:  ldarg.0
	IL_0001:  call	   void System.Threading.Thread::SleepInternal(int32)
	IL_0006:  ret
  } // end of method Thread::Sleep

Problem is that because of how it is sequenced ldarg.0 and the call are merged into 1(as you can see in the disassembly below).

  .method public hidebysig static void  Sleep(int32 millisecondsTimeout) cil managed
  {
	// Code size	   7 (0x7)
	.maxstack  8
	IL_0000:  ldarg.0
00000000  push		ebp  
00000001  mov		 ebp,esp 
00000003  push		eax  
00000004  mov		 dword ptr [ebp-4],ecx 
00000007  cmp		 dword ptr ds:[009F21C8h],0 
0000000e  je		  00000015 
00000010  call		76E2D1F9 
00000015  mov		 ecx,dword ptr [ebp-4] 
00000018  call		76CC60EB 
	IL_0006:  ret
0000001d  nop			  
0000001e  mov		 esp,ebp 
00000020  pop		 ebp  
00000021  ret  
  }

So does anyone know how to build mscorlib as a debug dll with maximum sequence points(to prevent the instructions from being merged)?

Also how do you handle methods that have generated bodies? (for example Thread.SleepInterval)

  .method private hidebysig static void  SleepInternal(int32 millisecondsTimeout) cil managed internalcall
  {
  } // end of method Thread::SleepInternal

Any help/tips would be greatly appriciated.

On a side note

Can you build native instructions into a .net exe with ilasm? Like I noticed with MonoCecil that there is a "native" flag. What is the "native" flag for(asking this because I compiled a mixed mode assembly and it seemed to convert all the native instructions to msil(from the looks of it). Just wanna clear this all up)?
